Question 1 of 5
A nurse is providing teaching to a client who has a new prescription for theophylline, a sustained-release capsule. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: C
Rationale:
Correct
Answer: C - "I will need to have blood levels drawn."
Rationale:
1. Theophylline is a medication with a narrow therapeutic range, requiring monitoring of blood levels.
2. Regular blood tests help ensure the medication is at a safe and effective level in the body.
3. Monitoring blood levels helps prevent toxicity or subtherapeutic levels.
4. Options A, B, and D are incorrect as they may lead to incorrect dosing or administration of the medication.
Question 2 of 5
A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose?
Correct Answer: A
Rationale: The correct answer is A: 500 mg per dose.
To calculate this, first convert 2 g to mg (1 g = 1000 mg, so 2 g = 2000 mg).
Then, since the dose is to be given every 6 hours, divide the total daily dose (2000 mg) by the number of doses per day (4 doses) to get 500 mg per dose.
Choices B, C, and D are incorrect as they do not align with the correct calculation.
Question 3 of 5
A nurse is preparing to administer an antibiotic via intermittent IV bolus to a client who is already receiving an infusion of 0.9% sodium chloride at 100 mL/hr. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Hang the secondary infusion higher than the primary IV infusion. This is to ensure that the antibiotic is infused first and at a faster rate than the maintenance fluid, preventing dilution of the antibiotic. Placing the secondary infusion higher allows gravity to push the antibiotic into the bloodstream before the maintenance fluid. Having another nurse verify the medication (choice
A) is a good practice but not directly related to the administration process. Disconnecting the primary IV infusion (choice
C) would interrupt the maintenance fluid, causing potential harm to the client. Flushing the IV site with sterile water (choice
D) is not necessary in this case and could introduce contaminants.
Question 4 of 5
A nurse is assessing a client who is receiving clindamycin. Which of the following findings should the nurse identify as an adverse effect of this medication?
Correct Answer: C
Rationale: The correct answer is C: Watery diarrhea. Clindamycin is known to disrupt the normal balance of gut flora, leading to an overgrowth of Clostridium difficile bacteria, which can cause watery diarrhea. Hypertension (choice
A) is not a common adverse effect of clindamycin. Agitation (choice
B) is more commonly associated with stimulant medications. Blurred vision (choice
D) is not a typical side effect of clindamycin. In summary, watery diarrhea is the most likely adverse effect of clindamycin due to its impact on gut flora.
Question 5 of 5
A nurse is assessing the vital signs of a client who is taking amiodarone. The nurse should anticipate which of the following findings as an adverse effect of the medication?
Correct Answer: C
Rationale: The correct answer is C: Bradycardia. Amiodarone is a medication used to treat arrhythmias but can cause adverse effects on the heart, including slowing down the heart rate (bradycardia). This is due to its effect on the electrical conduction system of the heart. Fever (choice
A) is not a common adverse effect of amiodarone. Hypertension (choice
B) is not typically associated with amiodarone use. Bradypnea (choice
D), which is slow breathing, is not a common adverse effect of amiodarone.
Therefore, the most anticipated adverse effect in this scenario is bradycardia.
